Haven't changed the rev limiter yet so it's still at 7300 rpm. Think I got to 6500 ish on one.
Any chance of a vid with running it to the redline? I'm curious to see what it sounds like, as my exhaust will probably have a slightly
different configuration.

No problem....soon as we get some nice weather here in sunny Cumbria. Tomorrow looks promising.
I recorded those with the skeleton back on will try and get some flyby video as well from the outside see how loud it is from the roadside when my
ears aren't 3 feet from the exhaust tip!
I know what you mean. It was a revelation when someone filmed my Indy Bird for the first time. I was really surprised at just how different it sounded
from the outside and with no helmet on.

Have borrowed a calibrated sound level meter from our HSE bloke at work to see how loud it really is. Of course it's throwing it down and I
realised I had broken a front spring on my Mondeo today on the way to work! Bugger.

That is brutal, not to mention disappointing! Just remember, that they tend to measure from behind, and sound dissipates and diminishes exponentially
with distance. In other words, a little bit farther away, makes for a very different reading.

Building: Built - V6 Fury , V6 Mx5...what next ?

Do you have a balance pipe ? I run a small pipe just after the collectors from side to side , which will lower the tone a lot (and improve the sound
from the drivers seat , much better than hearing half a V6)
Dont know if it makes it any quieter , but it may help ?
No I don't have a pipe linking the banks. Not sure how I could do it.
I think the simple answer is bigger or better silencers. Doing it on the cheap with universal silencer got me in the road but the pair cost less than
one decent repackable.
This is something I'm unsure of with my build. I'm currently planning on running a pair of large bike cans on my, but with a X piece about
18" back from the end of the collectors so I've not idea what so ever as to how it will sound.
You could put a cross pipe in as Claire does, but since you're manifolds point away from the engine, as opposed to down the side of it as
Claire's and mine will, fitting side pipe will be a PITA as it'll have to run round the engine some how, and I'm not sure if
it'll be worth the effort involved. Bigger silencers will certainly do it, as having seen a Caterham R500, I was surprised at just how big the
can was.

I think I need some quieter silencers. Was hoping to book Croft on the 25th May.
Any recommendations? I did fancy some from Paul Gooderham, as I know he used to be on here. Any other repackables I should look at?
God I hate listening to myself!

I hate my own voice as well.. Ha ha ha.
I wonder if the pulses of the exhaust are fighting each other with the un equal length pipes of the manifold? I will be starting mine this year once
the garage is sorted, same set up as you but with some little changes. I did wonder when you built them if the exhaust would run right, it's so
tight in there and you've made a good job with it, it's just something I thought might be a problem.

I still think a balance pipe will `soften' the sound a lot - I know it made a massive difference to mine . I ran it through the gap between the
sump and gearbox (where the Mx6 / Probe has it)
Heres mine minus the engine........
Also - we may have accidentally found a much shorter stater motor from a 323 - about 30mm shorter !

MK Indy engine conversion ZX9R to Mazda KLDE V6.
I thought it was about time I posted a diary of my engine conversion on my MK Indy. Finished and IVA’d the car in October last year and enjoyed a few
months of running after making and fitting a full cage post IVA. MK Indy RB968
Intention is to use this thread to record the conversion. I have made some videos and put on Youtube with photos on Flickr but wanted to write it up
as well.
I bought the Indy as a part started project, basically a rolling chassis which already included a Kawasaki ZX9R of B3/4 vintage. Initial testing and
IVA setup was fine and the bike engine went well but took a bit of getting used to the noise, the frenetic experience, gearchange etc. This year
however the gearbox started to become temperamental, there was a vibration at certain revs that was driving me up the wall and the lack of proper
reverse eventually meant I didn’t enjoy or use the car as much as I wanted to. I got the car originally to do some fast road driving and track days
but didn’t trust the engine/gearbox enough to go on a track day. It was time to change something.....
Initial idea was keep it simple and go for an MX5 engine and box, Megasquirt and changes to go to fuel injected from carbs. Then I saw clairetoo’s V6
/MX5 combo and the idea stuck.
I knew others had done V6’s in locosts and the all alloy low weight of the KLDE and decent power output with an easily sourced MX5 gearbox plus the
bonus of the Triumph throttle body setup for noise, look etc. had me hooked.
So in July I sourced a 71k mile KLDE from a Ford Probe, pulled the ZX9, exhaust, prop and started looking to test fit the engine. Description
Keeping track of the weight difference from the beginning the ZX9 engine wet with cradle weighed in just under 80Kgs. Description
and the KL weighed in dry without ancillaries at 112kgs Description
Once we had made a few minor adjustments to get the gearbox to sit far enough back and high enough in the tunnel we could test fit the engine and it
just fit. Description Description RB gearbox test fit Description

Hey Rich,
I will be building a car like yours, I'm driving around in a old MX6 with the 2.5L V6 just as a run about till I strip it.
So what I want to know is... The "Haynes Sports Car" is what I know as a Locost and a near copy to a Caterham. With yours being a MY Indy,
I wondered how different the front of the chassis is to accommodate the V6. I hope it's not smaller than yours??
Would you mind taking some measurements for me please? If it's smaller or exactly the same, I'm thinking about widening the chassis a bit
for the exhaust manifold but that means a lot of modding of the bodywork which I'd like to keep it standard sizes. I was just a bit concerned
about the tight space for the exhaust.
Across the front at the smallest gap near the front of the heads and at the back of the engine area where your coil pack is.
I edited a photo but this won't allow me to post it..

Another update to just about catchup with where I currently stand with this conversion.
I bought a 40 Amp Denso alternator so looked to make a mount and a way to adjuster the belt. With no ancillaries I decided to run a single belt from
the front pulley of the crank pulley and drive both water pump and alternator. This meant spacing the water pump pulley. Luckily we have machine shop
at work who made me a 28mm spacer.
I modded an adjuster from the rods used for my ZX9 gearchange. Seemed to do the job. Since the photo was taken I have remade the brackets out of 3mm
steel to stop any flexing.
I test fitted the engine to ensure the alternator cleared the chassis brace and to test fit the new prop. Trial fit KL RB
This revealed a(nother) ballsup as the tunnel chassis member I moved was now exactly where the joint on the prop was and guess what.......it just
touched when rotated.....so later that was cut and moved and welded back and re-painted RB new prop test fit cockup
While we were at it we test fit the starter again and tried turning the engine over on the starter for the first time in the car. Its been turned over
by hand and briefly on the garage floor but this is the first time with everything bolted together.
Cue the chuckle brothers (my Dad and Uncle) in charge of jump leads. Dad with his head in the footwell and my Uncle next to the clattery Xantia
neither of whom could hear the other.....this was the 3rd attempt.....
Success! no horrendous noises, and the belts went round.
When the engine came back out I installed the trigger wheel and made a bracket for the VR sensor. Both from trigger-wheels.com where I also bought a
Microsquirt and EDIS kit as I am copying Claire's alpha-n EDIS setup to keep it simple.
Made an inferior version of her coilpack mount as well which sits above the bellhousing. Coilpack mount RB
Early on it was obvious the bellhousing and clutch release arm were very close to the drivers footwell bulkhead. We had to remove the old clutch
master cylinder to get the gearbox in place so it was time to think of a solution. I was going to look at a vertical mount cylinder but these were
pricey so I had a look at the MX5 and saw it has the pedal mounted above . eBay visit later and I had a complete MX5 pedal and master cylinder. Cut
the pedal up as it was miles to long and mounted it as high as possible in the footwell and drill holes for the pushrod and mounts. RB gearbox clutch arm
All pretty tight but it will work. Going to make up a custom clutch hose to the standard MX5 slave cylinder and rod. RB clutch master cylinder MX5
So thats about up to date. Been tarting bits up and spending a small fortune on eBay. Got a intake manifold temp sensor, Claire is ordering me a set
of Magnecor plug leads and sending me a set of her throttle bodies.
Spent 20 minutes in Halfords finding a smaller M20 thread oil filter as the full size one hits the chassis rail....new one is off a Nissan Note!
Hopeful it will mean I don't need to run a remote filter. Small oil filter KLDE
Got a couple of days off work to start wiring....oh joy.
Rich
Hey,
I'd like to know where you got your ecu from? I understand that you are using vauxhall injectors and the triumph 595 throttle bodies. I've
got a spare KLDE 2.5L that I'm going to rebuild and put it in a RX8. I'll worry about the dash electronics later, I have a mate
that's an avionics engineer and he rekons it won't be too difficult to get the canbus electronics to work with a stand alone ecu.

...I am using a Microsquirt and EDIS trying to keep it simple as Claire seems to have done very successfully. This is my first venture into a
custom ecu so really I want to get it running and use it. ...
Thanks for that Rich, I should have been more detailed. I didn't know what EDIS stood for so what controls the injectors? Is the ecu for the
injection programmable? Have a cold running map? I need to be able to run the engine all year around as it will be my commuter.
I'm running a MX6 2.5L V6 on LPG, it's a new AEB system that I fitted myself and it's brilliant! To convert in terms that people
relate to, what I actually spend on LPG and petrol because it uses petrol to start and change over once it reaches 30c. On the motorway I get 55MPG
and hard driving I get 42MPG.
So.... To have the lovely sound of a V6 with diesel economy has driven me to this choice.
